Application aim March a1, 924. Serial No. 708,146.

The present invention has reference to internal combustion engines, and aims to provide novel means to be employed in conlifters, and at the same; time silencing the valve.

-Another is to provide a device'of this character which may be readily and easily positioned on valve stems orlifters now in use, eliminating the necessity of making alterations in the usual internal'combustion engine structure,-to apply the same.

With the foregoing and other objects in view which will appear as the description proceeds,

the invention resides in the combina-tion and arrangement of parts and in scribed and .claimed, "'it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of whattis claimed, without, departing from the spirit of the inven- I tion.

Referring to the drawing:

Figure 1 is an elevational view disclosing a device constructed in accordance with the invention, as positioned on a valve lifter.

Figure 2 1s an elevational view discloslng a silencer positioned on a valve stem.

Figure 3 is a plan view of the silencer.

Figure i is a vertical sectional view through a silencer. v

Referring to the drawing in detail, the reference character 5 indicates a valve lifter important object of the invention which is of the usual construction and which 'is employed for 'lifting the usual valve associated therewith and forming a part of an internal combustion engine. 1

The silencer includes a sleeve 6 and an upwardly extended flange 7, the sleeve being designed to fit over the valve stem or lifter on which the device is positioned to hold the silencer in position. V

Secured to thesile'ncer and held within the flange 7 is a disk 8 formed'ofrawhide or other suitable fibrous material to withstand wear, the disk being. des'i ed to-rest between the valve stem and lifter and cushion themovements thereof.

As shown by Figure 2, the device isillustrated as positioned on the upper end of overhead valve stems, the disk 8 being dis- I wardly and overlying a portion of the disk to secure the disk in position.

In testimony that-I claim the foregoing as 7 my own, I have hereto aflixed my signature.
